In HBO's defense it's kind of hard when GRRM hasn't finished his 6th book, so I really don't see a good conclusion coming from GOT. That is unless GRRM gets off his duff and finishes GOT, but even then I don't see a satisfactory ending. He seems to find a fascination in letting the "bad" guys win or changing the characters a little to make the more of a better person (King's Slayer?). I don't see any good in Ramsay at all and it would be foolish if the TV writers or GRRM did that to that character. An what a despicable ending if Ramsay came out on top.
